Definitions
- the object of this invention mainly refers to a structural improvement in a plastic electrolytic cell, which allows it to have a greater functionality and operating efficiency of electrolysis to obtain chlorine, alkalis and a variety of products through the use of a activated titanium electrode and cathode of steel or activated nickel or other metals suitable for the conventional ion exchange process and membranes and in addition to other uses in electrodialysis and electro-oxidation processes of chemical solutions.
- references cited above refer to cells whose structure differs from that requested, since they are very different and allows independent distribution of feeds at the same time, since it is also possible to visually inspect through the translucent restrictor hoses, the continuity of the flow , as is the same case as product discharges through an upper compartment that allows an over-level that ensures the filling of the anodic and cathodic tank section and separates the zone of turbulence from the membrane area, spilling through the translucent ringed hose that acts as a sight glass and to break the leakage current to the collecting tube.
- Our improvement also refers to a structure reinforced with protuberances, which serve to maintain the perpendicularity of the seal faces of the anode and cathode partition plate of the plastic frame and also in the grid crosses of the mentioned reinforcements a projection is projected.
- Figure 1 is a front view of the bipolar membrane plastic electrolytic cell, where most of the parts that comprise it are shown.
- Figure 2 is a side view of the cell.
- Figure 3A is a cross-sectional view of the right lateral arrangement of two pressed cells
- Figure 3B is a cross-sectional view of the left lateral arrangement of two pressed cells.
- bipolar membrane type electrolytic plastic cell The improvements to this bipolar membrane type electrolytic plastic cell, are based on the configuration of its structure, which allows the independent distribution of the brine feeds, through the use of an activated titanium electrode and an activated steel or nickel cathode or other metals suitable for the ion exchange process and membranes and in addition to other uses in electrodialysis and electro-oxidation processes of chemical solutions.
- the compartment (8) is the one that allows an over-level that ensures the filling of the anodic and cathodic tank section (not shown) and separates the turbulence zone from the area of the membrane (not shown) spilling down the translucent ringed hose (11) that acts as a sight glass and to break the leakage current to the collecting tube (12).
- Our improvement also refers to a structure reinforced with a protuberance, which serves to maintain the perpendicularity of the seal faces of the integral plastic injection dividing plate (24) of anode and cathode compartments of the plastic frame (1) and also in at the crossings of the grid of the reinforcements (not shown) mentioned, a pole (20) is projected that serves as support for the meshes (15) of the anode and cathode to maintain the perpendicularity of the next cell, and the minimum separation between electrodes that are required to achieve a lower voltage drop of the electrolytic cell that results in greater current efficiency and saving of electrical energy (KWh).
- FIG. 1 we can see the structure or preferably rectangular plastic frame (1) indicating the perimeter limit of the cell, where the low relief or depth (2) is indicated, in the entire surface of the frame that allows the formation of the deposit of the anode, where the integrated section of the distributor tube (3) integrated to the plastic frame (1) is represented by one of its lower side faces and, through the connector (4) and the restrictive flow hose (5), feeds on brine to the anode tank, the feed flow is restricted to maintain a residence time required for the electrolysis reaction, and a restriction for current leakage to the distributor (3), the spent brine and the products rise being blocked by the upper left section (6) which has no communication with the deposit of the low relief anode since it is blind, and allowing the discharge of the products and gases through the four perforations (7) that communicate to the upper right compartment that is the gas and liquid separator (8), the feed to the anode deposit can be among others depending on the electrolytes used, TREATED SALMUERA (SODIUM CHLORIDE OR POTASSIUM CHLOR
- the structure and configuration of the plastic frame (1) in addition to having independent integral discharges, also has a hose connector (13) at the bottom of the cell discharge, to install a sampling that allows the products to be analyzed before of mixing in the general collector, which determines the efficiency of the cell reaction.
- the anode and cathode electrodes have a plurality of contacts (14) that are welded around its diameter to the mesh (15), which covers the entire surface of the cell which is shown in a single section that corresponds to the electrode of the activated anode.
- the contact (16) is shown to come from the cathode electrode which has the same descriptions and parts shown for the activated anode electrode, it should be mentioned that only the contact materials (14) and the mesh (15) are different by the characteristics of the reaction, the union of the electrodes of the activated anode and cathode that may or may not be activated, is carried out in a conventional manner with screws and gaskets (not shown) that make electrical contact between them, by means of a plurality of perforations ( 17) evenly distributed along the cell surface below the mesh (15), depending on the equal number of even contacts (14) and (16).
- the upper support of the plastic frame (19) allows the separation and sliding of the electrolytic plastic cells with bipolar membrane along a lower insulating rail (not shown) of the cell module (not shown), without losing the necessary verticality to maintain the grouping while pressing the cells.
- two wheels (26) are integrated for sliding them in a pressed module.
- the plastic frame (1) also presents a series of holes (25) where small plastic bolts are placed that support (not shown) the gaskets and the membrane, which allow it to coincide with other perforations in the same position to be able to join two plastic frames with their respective anodes and cathodes, if they affect the seal area of the compartments.
- Figure 2 we can see a side view showing the integration of the lower distributor tube (3) and flow restrictor hose (5), discharge hose (11) and upper general collection tube (12).
- FIG. 3A A side section of the anode is shown in Figure 3A indicating two equal plastic frames (1) where an arrangement can be seen that contains a conventional ion exchange membrane (22) between each plastic frame, which covers the entire surface of the meshes (15) including up to the perimeter area that forms the lower plastic frame of the cell to seal both sides with the gaskets (21), which also make an integral seal with the sections of the upper deposits of the products and gases (8 ).
- the figure also shows a detail cut of the perforations (7) communicating to the above mentioned compartments.
- the figure also shows the integral plastic injection divider plate (24) that separates the anode and cathode compartments and that has an arrangement of protrusions or reinforcements that in addition to the resistance of the injection material being polypropylene or other thermoplastic for high mechanical and temperature resistance, a distribution of integral gridded reinforcements is added.
- Figure 3B shows the lateral section of the cathode indicating two equal plastic frames (1), and the same parts as Figure 3.
- the use of our device is not intended to be limited to the mentioned applications. but to claim any other that using the same device obtains the aforementioned purposes.
